IMPROVEMENT IN WHIFFLETREE ATTACHMENTS.

Specification forming part of Letters Patent No. 3 1,027, dated December24, 1861.

To all whom it may concern:

Be it known that I, CONRAD MARQUARDT, of Rhinebeck, in the county ofDutchess and State of New York, have invented anew and usefulImprovement in WVhiffletree Attachments for Two-Horse Vehicles; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making a part of this specification, in which Figure 1 is aplan or top View of myinvention; and Fig. 2, a transverse section of thesame, taken in the line 50 m, Fig. 1.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention relates to a novel means employed for attaching thewhiffletrees to the doubletree, as hereinafter fully shown anddescribed, whereby the whiifletrees may be readily adjusted on thedoubletree nearer to or farther from its bolt, and the draft regulatedfor either horse, as occasion may require.

It is quite frequently the case that one horse of a team is capable ofdrawing more than the other, and in the ordinary whiffletree attachmentthe stronger horse pulls against or has a tendency to draw back theweaker one, and the efficiency of the team is greatly reduced thereby.

The object of the within-described invention is to obviate thisdifficulty, and to this end I have the back edge of the doubletreeprovided with notches or racks at each end, in which the whiffietreeclasps or links are fitted and retained therein by a spring,substantially as hereinafter described.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a doubletree, which may be of the usual form anddimensions, and B B are two racks or notched metal bars, which aresecured to the back edge of the doubletree-one near each end-as shown inFig. 1.

To the front edge of the whiffletree there are attached metal plates CC, said plates being directly in front of the racks B B.

D D represent whiffletrees,which may also beof the usual form andlength. Each whiffletree has a link E attached to it near its center.These links are of rectangular form, and they are attached to thewhiffietrees by being fitted in eyes or loops a, which are secured tothe whiffletrees. These links E E are placed on the doubletree, the backends of the links fitting in the racks B. Thelinks are retained in theracks B B by means of springs F F, which may be of spiral form, andplaced on pins 1), attached to the back edges of the whiffletrees. Thesprings F bear against the plates C at the front edge of the doubletreeand have a tendency to keep the whiflletrees forced outward from thedoubletree, and consequently keep the links E in the racks. By thisarrangement it will be seen that the whifiletrees may be readily shiftedon the doubletree, so that the links may fit in any of the notches ofthe racks and the draft-connection of either horse regulated as desired.It will be seen that when the Vehicle is being drawn along the links Ewillbe retained in the racks by the pull of the whiffletrees, but whenthe draft movement ceases the springs F perform that function.

The invention is extremely simple and will not augment in an appreciabledegree the usual cost of construction. v

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

Attaching or connecting the whiffletrees D CONRAD MARQUARDT.
